Update on tooth color measurement by visual and spectrophotometer methods

Abstract

Introduction: Tooth colour assessment is a crucial aspect in aesthetic dentistry, as it influences the design of restorative and aesthetic treatments. There are various methods for assessing tooth colour, the most common being the visual method and the use of spectrophotometers. Each has advantages and disadvantages that can affect the accuracy and reproducibility of the results.
Development: The visual method consists of comparing tooth colour with standardised shade guides. This approach is accessible and easy to implement, but its subjectivity can lead to variations in colour perception between different operators. Factors such as lighting, visual fatigue and environmental conditions can influence the assessment, compromising the consistency of the results. On the other hand, the spectrophotometer offers an objective measurement of tooth colour by quantifying the light reflected by the teeth at different wavelengths. This method provides accurate and repeatable data, eliminating the subjectivity of the visual method. However, its cost and the need for technical training can be limitations in its widespread use.
Conclusions: Both methods have a significant role in tooth color assessment. While the visual method is more accessible and practical in clinical settings, the spectrophotometer offers superior accuracy and objectivity. The choice between the two will depend on the specific treatment needs and available resources. For optimal results, it is suggested to consider a combined approach that takes advantage of the strengths of each method.
